Granted: 1991-04-02
Abstract: ABSTRACT OF THE DISCLOSURE         A molded case circuit breaker includes a movable upper electrical contact carried by a contact member having an end portion with an arcuate cam surface formed thereon for engaging an outwardly projecting cam surface of a leaf spring.  The leaf spring is secured to and disposed around an enlarged portion of a rotatable cross-bar of the operating mechanism of the circuit breaker.  The leaf spring has an outwardly protruding cam surface and is mechanically configured to provide sufficient biasing force to the end portion of the movable upper electrical contact member to enable the upper electrical contact member and upper contact to move in unison with the cross-bar during normal operation of the breaker.  Upon the occurrence of a high level short circuit or fault current of sufficient magnitude, the upper electrical contact member and upper contact rotate and the arcuate cam surface thereof is moved against the then stationary cam surface of the leaf spring.  The arcuate cam surface of the leaf spring and the arcuate cam surface of the end portion of the contact member are configured to provide decreased biasing force as the upper electrical contact member rotates to its BLOWN-OPEN position.  A detent or groove is formed along the arcuate cam surface of the end portion of the contact member for receiving the outwardly projecting cam surface of the leaf spring to retain the movable upper electrical contact and contact member in a BLOWN-OPEN position, thereby minimizing the possibility of contact restrike.

Title: Preparation of particulate radioactive waste mixtures
Inventor: RAMM ERIC J
IPC: G21F9/00
Filed: 1986-10-28
Granted: 1991-09-10
Abstract: ABSTRACT OF THE DISCLOSURE            A dry, pourable particulate mixture of nuclear waste and synthetic rock-forming components is produced by supplying the rock forming components in dry particulate form to a mixer, supplying the nuclear waste in liquid phase and operating the mixer to distribute the waste substantially uniformly through the synthetic rock components; the mixture is calcined to produce a precursor powder which is adapted to be used in a hot pressing process to form synthetic rock throughout which the radioactive nuclear waste is distributed and immobilised.  A reducing gas atmosphere is preferably maintained in the calcining process stage, the gas being for example pure hydrogen or a mixture of hydrogen in nitrogen in proportions which are non-explosive.  A screw type or paddle type conveyor can be used for the mixing and calcining stages although the calcining can be effected in a vertically downwardly directed tube device having associated heating means such as microwave heating.

Granted: 1992-08-11
Abstract: ABSTRACT    What  is  disclosed  is  an  electronic  equipment housing  that  provides  easy  access  to  electronic equipment inside via a hinged top panel and a clear plastic safety panel below it.  Inside the housing are cable raceways at the top front and top rear that are in line with raceways in adjacent housings to permit many cables to be contained inside the housings.  The raceways and cables therein do not interfere  with   convection  cooling  inside   the housings and do not interfere with top access to the equipment. Relatively high heat generating equipment such as power supplies are mounted to one side of the interior of a housing and separate fans cool the power  supplies  with  one  flow  of  air,  and  other equipment in the housing is cooled by a separate flow of air drawn by other fans. One housing is used to  house  common system  equipment  and  is  always located at one end of a line of housings. The common housing has a side mounted connector arrangement, with the connectors being mounted on swing out doors to provide access to change the connectors or wiring thereto.  The connectors ace organized that cables coming   from  other   adjacent   housings   to   the connectors may all be the same length. The front and rear panels on all housings have slots that permit cooling air  flow,  and conductive screening behind the  slots  minimizes  radio  frequency  interference (RFI).   In  addition,  the  top,  front  and  side removable panels have gaskets to suppress RFI.

Title: Assay to detect the presence of live virus in vitro
Inventor: ZELDIS JEROME B
IPC: C12Q1/70
Filed: 1987-07-28
Granted: 1993-08-03
Abstract: ABSTRACT       An assay to detect the presence of live hepatitis viruses in vitro.  Bone marrow cells or leukemic cell line cells are exposed to a body fluid or biological preparation to be tested and the cells are placed in suspension.   When using bone marrow cells growth factors to the bone marrow stem cells are added.  It has been determined that presence of a live hepatitis virus suppresses the growth of colonies of the stem cells.  Therefore, if the number of colonies growing in the mixture are less than that number present in a culture of cells exposed to a sample that has been determined to contain no live virus, live hepatitis virus is present in the sample tested.  The assay is particularly useful to determine the presence of live hepatitis B virus in a vaccine.

Abstract: Title:  IMPROVED TRAILER AND TRAILER UNLOADING SYSTEM                       Inventor:                  E. Dale Fenton ABSTRACT OF THE DISCLOSURE      A trailer for unloading onto the ground or like surface using an unarticulated frame and no power sources other than the tractor or prime mover is disclosed.  The frame supports three rows of overlapping transverse rollers and has a tail-end roller substantially across its width.  A wheeled car-riage is mounted to the underside of the frame, so that it can be longitudinally shifted.  When mounted on a conven-tional "fifth wheel" connection to the tractor, shifting of the carriage forward lowers the tail end of the frame which pivots downward about the connection to the trailer.  Shift-ing the carriage back raises the tail.  A pair of ground rollers is provided at the tail of the trailer which con-tacts the ground as it is lowered.  A load may be placed onto the ground by unlocking the carriage, applying the brakes to the wheels of the carriage and backing up the tractor-trailer.  When the trailer end is lowered so that the ground rollers are on the ground, the trailer is stopped, the load is unstrapped, and the tractor trailer driven forward, out from under the load which is thus placed on the ground.  Thereafter, by applying the carriage brakes again while driving the rig forward, the frame is returned to its raised tail position, the carriage relocked, and the unloaded rig can be driven on the road.
